i fix equinox headgaskets. i got one last week. idled ok. no bad sounds. i pulled heads. did gaskets. put it back together and now i have a noticeable valve train knock. not ”bad” but more then before. i saved old oil but cant really do a viscosity check. could oil be issue?

its a 2008 3.4 motor. timing chain. not an ecotec motor. just a old school 2.8/3.1/3.4 version.
